peritectic

The Al-based amorphous alloy forms in the peritectic reaction and peritectoid reaction, and its growth velocity is slow.

分析了铝基准晶合的组织与相变特征，铝基准晶的生成通常为包晶、包析反应，其长大速度较慢。

The star cracks in macrostructure appear in some hypo-peritectic continuous cast alloy blooms and these cracks cannot be stuck completely by hot rolling reduction ratio,macroetching testing and SEM.

一些亚包晶合钢连铸大方坯出现低倍星状裂纹,在一定的压缩比下经轧制仍不能完全消除这种低倍缺陷。
